Are there any documented instances
where flesh of some kind is necessary? (Someone I know has for many
years not touched meat. She recently became very ill (I don't know the details).
Concerned family took her to a nutritionist doctor who prescribed eating
fish. She has recovered dramatically.)
from a member of ivu-sci:
It is practically impossible to answer questions such as this without
full details of the illness and whether any form of medication (other
than the advice to eat fish) was used. One cannot even say for certain
whether the addition of fish to the diet was actually responsible for
the recovery as there are cases of spontaneous remission.
Since all of the nutrients in meat can be obtained from other sources
I cannot see any situation in which it is strictly necessary to eat meat.
The same probably goes for fish, although like meat, fish is a concentrated
source of several nutrients which are less easy to obtain on a veg*n diet.
A good example are the longer chain omega-3 fatty acids (EPA & DHA) of
which fish and seafoods are the main source. Vegans must convert alpha-linolenic
acid (obtained from flax, canola (rapeseed) and soya oils) into these
essential fatty acids, and it may be that the person in question was not
consuming these foods.
- another member of ivu-sci suggests that the problem described above
might have been due to a lack of Vitamin
b12

Where is a detailed table showing the percentage of various nutrients
in all kinds of foods?
from a member of ivu-sci:
Information of this sort can be obtained from food composition tables
such as McCance & Widdowson's The Composition of Foods (published in the
UK by the Royal Society of Chemistry). Your local library may have a copy.
On the internet, the University of Illinois' Nutrition
Analysis Tool (NAT) will give you nutrient information on specified
foods/diets.
Is it possible to continue a vegetarian diet if you have 'diverticulosis'
or 'irritable colon'?
from a member of ivu-sci:
"Diets high in insoluble fibre (especially coarse wheat bran) speed up
transit time through the gut, increase stool weight and relieve constipation.
They are also associated with a reduced risk of diverticular disease and
are of benefit in relieving at least some of the symptoms in those with
established diverticulitis [1]."
Therefore, a high-fibre vegetarian diet would be a good diet to follow
for diverticulitis sufferers. Indeed, there is some evidence that vegetarians
may have a lower incidence of diverticular disease [2]. "However, it is
preferable for fibre intakes to be increased through the consumption of
a variety of cereals and vegetables rather than relying on extensive use
of bran supplements [1]."

Is it safe for a diabetic to become vegetarian/vegan?
from a member of ivu-sci
Not only is it perfectly safe, it may even prove beneficial. According
to the British Diabetic Association, dietary recommendations for diabetics
encourage a high intake of complex carbohydrates and dietary fibre and
a low intake of fat, particularly saturated fat. Vegetarian diets tend
to match these recommendations more closely than non-vegetarian diets.
In their position paper on vegetarian diets, The American Dietetic Association
state that "scientific data suggest positive relationships between a vegetarian
diet and reduced risk for several chronic degenerative diseases and conditions,
including obesity, coronary artery disease, hypertension, DIABETES MELLITUS,
and some types of cancer" (my emphasis).
They also note that "type 2 diabetes mellitus is much less likely to be
a cause of death in vegetarians than nonvegetarians, perhaps because of
their higher intake of complex carbohydrates and lower body mass index"
(body mass index is a measure of obesity). The text of the ADA position
paper can be found on the web at www.eatright.org/adap1197.html
from a another member of ivu-sci
In my opinion, there are no special dietary requirements for diabetics
that can not be met with a PROPER veg*an diet. Your diet should include
plenty of B-vitamin rich foods including whole grain breads and green
leafy vegetables. Avoid refined carbohydrates such as spaghetti, white
bread, etc. Regardless of your type of diabetes, carefully monitor your
blood sugar levels as they may vary widely as you make the switch.
Is there a non animal form of glucose lowering agents for diabetics?
from a member of ivu-sci
Do you mean glucose-lowering meds like Glucophage? Best bet is to check
the PDR or other drug resource likely available online.
(further answers wanted)
from a reader in India:
There is a vegetable called bittergourd (Karela in Hindi) which is quite
popular in India to lower or prevent diabetes. Also there is a spice called
Methi (in Hindi don't know the English equivalent) which is to be soaked
overnight and consumed on empty stomach the next morning with a glass
of buttermilk. This too helps in lowering diabetes
Does a vegetarian diet meet the full needs of the human body?
from a reader in the USA:
Yes. We weren't always meat eaters. There are entire populations today
that are vegetarians - and they have fewer health problems that meat eating
populations do.
What foods does vegan nutrition include and exclude?
from a reader in the USA:
A vegan diet exludes all animal products. No flesh, dairy, eggs, or their
derivatives.
